Lindsey Hutchinson and husband Todd — both with design backgrounds and a passion for gardening — decided to build “green curtains” or exterior trellises covered in edible vines, according to the Statesman. The 15-foot living walls will shade the home and rain barrels from the sun, but the Hutchinson’s also intend to harvest the vines for grapes, passionfruit, and Scarlet Runner Beans. Thusly, these green curtains perform double duty in the form of food production and energy conservation. What a great idea!
